Abstract
A master unit for use within a distributed antenna system includes circuitry configured to: manage a plurality of radio units of the distributed antenna system by communicating management plane messages with the plurality of radio units of the distributed antenna system; receive downlink control plane messages, downlink user plane messages, and uplink control plane messages from a distributed unit of an open radio access network; and copy and forward the downlink control plane messages, the downlink user plane messages, and the uplink control plane messages to the plurality of radio units of the distributed antenna system.
Claims24
A master unit for use within a distributed antenna system, the master unit comprising:
- circuitry configured to:
- manage a plurality of radio units of the distributed antenna system by communicating management plane messages with the plurality of radio units of the distributed antenna system;
- receive downlink control plane messages, downlink user plane messages, and uplink control plane messages from a distributed unit of an open radio access network;
- and
- copy and forward the downlink control plane messages, the downlink user plane messages, and the uplink control plane messages to the plurality of radio units of the distributed antenna system.
A distributed antenna system, the distributed antenna system comprising:
- a master unit communicatively coupled to a distributed unit of an open radio access network implementing a shared cell;
- a plurality of radio units communicatively coupled to the distributed unit, wherein each of the plurality of radio units includes circuitry for exchanging radio frequency signals with at least one user equipment;
- and
- wherein the master unit is configured to:
- manage the plurality of radio units of the distributed antenna system by communicating management plane messages with the plurality of radio units;
- receive downlink control plane messages, downlink user plane messages, and uplink control plane messages from the distributed unit of the open radio access network;
- and
- copy and forward the downlink control plane messages, the downlink user plane messages, and the uplink control plane messages to the plurality of radio units.
A method comprising:
- managing a plurality of radio units of a distributed antenna system by communicating management plane messages between a master unit of the distributed antenna system and the plurality of radio units of the distributed antenna system;
- receiving downlink control plane messages, downlink user plane messages, and uplink control plane messages from a distributed unit of an open radio access network at the master unit of the distributed antenna system;
- and
- copying and forwarding the downlink control plane messages, the downlink user plane messages, and the uplink control plane messages from the master unit of the distributed antenna system to the plurality of radio units of the distributed antenna system.
